MAX ROENSPIESS AND MATTHEW FLYN N, OF ST. JOSEPH, MISSOURI.

MACHINE FOR CURVING AND STRAIGHTENING STEEL RAILS.

SPECIFICATION forming part of Letters Patent No. 418,229, dated December31, 1889.

Application filed June 24, 1889.

To aZZ whom it may concern.-

Be it known that we, MAX ROENSPIEss and MATTHEW FLYNN, citizens of theUnited States, residing at St. Joseph, in the county of Buchanan andState of Missouri, have invented certain new and useful Improvements inMachines for Curving and Straightening the Cold Steel Rails ordinarilyused by Railways; and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

Figure 1 is a perspective view of the machine. Fig. 2 is an endelevation of the machine. Fig. 3 is a cross-section of Fig. 2. Fig. 4 isa side elevation of the machine. Fig. 5 is an enlarged detail view ofthe channel-iron with nuts on. Fig. 6 is an enlarged detail view of oneof the boxes through which the journal of the main roller passes. Fig. 7is an enlarged detail view of the lower box of the main roller, and Fig.8 is an enlarged detail View of one of the boxes for the small rollers.

Similar letters refer to similar parts throughout the several views.

Our invention consists of the following-described two principal parts:first, a frame constructed out of six-by-six-inch oak or other suitabletimber, consisting of two sills a a, two uprights b 17, four horizontalposts 0 c c c, and two caps (1 cl; second, two iron rollers e e, turnedout at o o o 1;, so as to ad Inita steel rail, and 'one iron roller f,also turned out so as to admit a rail at w 20. Each roller has a journalof suitable dimensions to run in iron. boxes. 1

On the upper end of the journal of roller f is a cog-wheel g, propelledby two cranks h h, Fig. 4, which are fastened to journal 1', and towhich is fastened an endless screw 70. Af-

ter a steel rail is placed between the rollers enough pressure to bendthe rail to the required curve, or to straighten a rail, is applied bymeans oftwo jack-screws Z Z, Fig. 2, which work in iron plates m m.These plates are each held in place by two rods an, which go through theplates and frame, and also by channel-irons 0 0, Fig. 3, which arebolted to the horizontal posts 0 c c c, the ends of the channel-irons tobe rounded, with thread and nuts. Rods n n n n and channel-irons 0 0 0 0also serve as truss-rodsto the frame. The endless screw 7c is held inposition and gear by two iron rods 00 00, which go through the box p andboxes q q. The boxes q q are held down by two bolts 4" 1', which passthrough the lower part of the boxes q q, just outside of the upperhorizontal posts 0 0, nuts being on the ends of the bolts '2" r, and aplate of iron 8, which reaches across the bottoms of the upperhorizontal posts 0 0. Boxes uuuu are of iron, constructed of suitablesize for journals.

25 represents the lower box of the main roller f, and jjj represent thejournals of the rollers.

Bolts y y in each box it, as shown in Fig. 8, are for the purpose ofholding to in place on sill a. Bolts 2 z, Fig. 2, are for the purpose ofholding upper and lower halves of box q together. J ack-screws ZZ bearagainst thejournal-boxes t and 19, and these journalboxes slide alongchannel-irons o 0.

The amount of pressure to be applied to secure the degree of curvatureof rail desired will be shown by an indicator to be attached to one ofthe boxes q. After a rail is placed between the rollers at o and w andthe neoessary pressure is applied, the rail is drawn through the machineby the revolving of endless screw 16 by cranks h h.

For convenience the machine may be put upon a rubble-car, which shouldbe supplied with a threeinch roller on each end to help carry the Weightof rail.

From the foregoing description it will be seen that our invention doesnot accomplish the purpose for which it is intended by kinking a rail,but in its operation curves or straightens a rail of any weight truer,faster, and cheaper than any machine constructed for a similar purpose.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. The combination of frame consisting of sills a a, uprights b 1;,horizontal posts a c c 0, caps d d, with rollers e e and f,channel-irons 0 0 0 o, cog-wheel g, endless screw is, jackscrews Z Z,journals '0' and j jj, boxes pt q q u u u u, plates m m and s, rods a:as and n n n n,

bolts r r, y y, and z z, and cranks h h, for the ;a a, uprights b b, andcaps d d, substantially 1o purpose specified, substantially asdescribed. as described, for the purpose specified.

2. The combination of rollers e c, turned In testimonywhereof weaffixoursignatures out at o '0 v o, and roller f, turned out at w in presence oftwo Witnesses.
